About 2,000 miles farther .

Thirty-six officers from the Tucson , Arizona , Police Department are in Pittsburgh as part of the G-20 security force . They were asked to assist by Pittsburgh officials as part of a Department of Homeland Security rapid response team .

Officers from departments in several cities , including Cleveland , Ohio ; Miami Metro Dade , Florida ; Baltimore , Maryland ; and Chicago , Illinois , were sworn in as part of the massive security effort , but Tucson wins the prize for the greatest distance traveled . Watch how Pittsburgh has prepared for protests ''

`` There 's a standardization in training , '' Tucson Lt. Paul Sayre said . Departments brought in to assist have undergone similar preparations in techniques and crowd control .

The Arizona officers were asked to come to Pittsburgh after taking part in the protection effort at the Republican National Convention in 2008 in St. Paul , Minnesota .

The downtown Pittsburgh street on a morning with temperatures in the 50s was nothing like a typical day for the officers . `` It 's a different environment , '' Sayre said -- but the job was the same . `` We 're excited to be here . It 's a lot of fun . ''

`` Our role is to support Pittsburgh , '' said Capt. Perry Tarrant , commanding the Tucson team .

The additional help protecting downtown locations `` gives Pittsburgh the flexibility to send its officers where needed , '' Sayre said .
